No gassy FPR hose. Can check PCV soon. TB cleaning and tune-up are prime suspects due to neglect but all those things have been tended to in the not-so-distant past. Maybe a Torque-ing (the app) can shed some light on it too if I pay attention. My TB has a broken screw in it so I need to just snag the 02's tomorrow and swaperoo after freshening it up. It has no other issues I can detect, this is currently an annoyance only but a new one.
